“extra money to burn” is kind of a funny choice of words, because gold bugs talk about the “intrinsic value” of paper money ultimately being its use as firewood or toilet paper. When there is a lot of “extra money” to burn sloshing around, it might be better to put it into something less likely to be so easily produceable. like gold. but i like your train of thought. might do better renting out metal detectors at nice beaches though, since mining is pretty hard work.
